Analysis

During a spray run the pilot experienced a power loss. After pulling up to 100 feet AGL and turning 90 degrees the engine ceased to operate. The pilot completed a forced landing in a nearby soft wheat field and after rolling approximately 300 feet the aircraft became inverted. Inspection of the engine revealed that the number 6 cylinder had separated where it attaches to the cylinder head and in the area of an old crack.
